Former Florida Gov. Jeb Bush will campaign on Friday for one of his successors, current Gov. Rick Scott.

Bush, who is considering a run for the Republican nomination for the White House in 2016, will visit "a business in Homestead to highlight proposals to keep Florida working," a Scott spokeswoman told the Tampa Bay Times.

Scott is locked in a heated re-election battle with another former Sunshine State governor, Charlie Crist.

Bush, 61, served in the statehouse from 1999 to 2007. Scott came in 2011, after Crist served one term as a Republican. Crist is now running as a Democrat.

Last month, Bush joined with former bankers from Credit Suisse and Lehman Brothers Holdings to create a private-equity firm in Coral Gables, Fla., Bloomberg reported.

The move raised further speculation that Bush might launch a presidential bid.
